Abstract

Taking the installation construction of super large radial gates of Nam theun1 hydropower station in Laos as an example, due to the lag of civil construction period and the dam structure, it is not convenient for large lifting equipment to enter the installation face directly. This paper introduces the application of "Bailey beam + Gantry crane" lifting radial gate technology under the conditions of large construction interference, heavy construction task and tight construction period, The installation of super large multi hole radial gate was successfully and quickly realized, which ensured the water storage and power generation schedule of the power station. According to the normal construction sequence, the radial gate of the spillway should be installed normally with large lifting equipment in the open hole state after the civil construction junction, and the upper concrete construction should be carried out after the radial gate is installed. During the construction of the dam and the arc gate, the civil engineering is in the process of sluice construction, the concrete of the dam body is rising, the multi-process and multi-professional construction is intensive, and there are multi-directional intersecting operations, which causes great construction interference. Combined with relevant cases, this paper focuses on the installation technology of super large radial gate in the high temperature and Rainy Zone and the complex environment with limited construction site conditions, so as to provide reference for the implementation of similar projects and actively explore new advanced technology for the industry.
